Method for merging voice after Beidou short message fragment transmission

The invention discloses a method for combining voices after Beidou short message fragment transmission. The method comprises the following steps: step 1, communication receiving; step 1, communication receiving; step 3, signal processing; step 4, characters integrating; step 5, voice generation; step 6, communication recording; and step 7, information merging. According to the method and the device, a plurality of voice files of the same sending end are merged, so that the information integrity of voice is improved, the receiving end can conveniently check and forward the voice information, the user experience is improved, invalid noise generated by communication network fluctuation in the communication signal is eliminated through self-adaptive filtering and noise reduction processing, the communication stability of the Beidou system is improved, the distortion risk of a communication signal is reduced, meanwhile, through the communication content record positioned in real time, the receiving end can conveni
